W A R N I N G
HIGH VOLTAGE
AC drives contain high voltage when connected to AC mains input, DC supply, or load sharing. Failure to perform installation,
start-up, and maintenance by qualified personnel can result in death or serious injury.
Only qualified personnel must perform installation, start-up, and maintenance.
-
W A R N I N G
UNINTENDED START
When the drive is connected to the AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of death,
serious injury, and equipment or property damage. The motor may start by activation of an external switch, a fieldbus command,
an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared fault condi-
tion.
Press [Off] on the LCP before programming parameters.
-
Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended motor
-
start.

Safety
N O T I C E
The [Off/Reset] key is not a safety switch. It does not disconnect the drive from mains.
W A R N I N G
DISCHARGE TIME
The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be
present even when the warning indicator lights are off.
Failure to wait the specified time after power has been removed before performing service or repair work could result in death or
serious injury.
Stop the motor.
-
Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and
-
DC-link connections to other drives.
Wait for the capacitors to discharge fully. The minimum waiting time is specified in the table Discharge time and is also visible
-
on the nameplate on top of the drive.
Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors
-
are fully discharged.
Table 1: Discharge Time
Leakage current (>3.5 mA)
Follow national and local codes regarding protective earthing of equipment with a leakage current >3.5 mA. AC drive technology implies high frequency switching at high power. This generates a leakage current in the ground connection. A fault current in the drive at the output power terminals might contain a DC component, which can charge the filter capacitors and cause a transient ground current. The ground leakage current depends on various system configurations including RFI filtering, shielded motor ca­bles, and drive power.
EN/IEC61800-5-1 (Power Drive System Product Standard) requires special care if the leakage current exceeds 3.5 mA. Reinforce Grounding in 1 of the following ways:
Grounding wire of at least 10 mm2 (8 AWG).
2 separate ground wires both complying with the dimensioning rules.
See EN 60364-5-54 § 543.7 for further information.
Using RCDs
Where residual current devices (RCDs), also known as earth leakage circuit breakers (ELCBs), are used, comply with the following:
Use RCDs of type B that can detect AC and DC currents.
Use RCDs with an inrush delay to prevent faults due to transient ground currents.
Dimension RCDs according to the system configuration and environmental considerations.
Motor thermal protection
Motor overload protection is possible by setting parameter 1-90 Motor Thermal Protection to [4] ETR trip. For the North American market: Implemented ETR function provides class 20 motor overload protection, in accordance with NEC.
Installation at high altitudes
For altitudes above 2000 m (6562 ft), contact Danfoss regarding PELV.

3.6 Connecting to Mains and Motor

The drive is designed to operate all standard 3-phased asynchronous motors. The drive is designed to accept mains/ motor cables with a maximum cross-section of 4 mm2/10 AWG (M1, M2, and M3), and a
maximum cross-section of 16 mm2/6 AWG (M4 and M5).
Use a shielded/armored motor cable to comply with EMC emission specifications, and connect this cable to both the decou­pling plate and the motor metal.
Keep motor cable as short as possible to reduce the noise level and leakage currents.
For further details on mounting of the decoupling plate, see VLT® Micro Drive FC 51 Decoupling Mounting Plate Instructions.
Also see the chapter EMC-correct Electrical Installation in the VLT® Micro Drive FC 51 Design Guide.

Programming

4.2 Programming on Automatic Motor Tuning (AMT)

Run AMT to optimize compatibility between the drive and the motor in VVC+ mode.
The drive builds a mathematical model of the motor for regulating output motor current thus enhancing motor performance.
Run this procedure on a cold motor for best results. To run AMT, use the numeric LCP (NLCP). There are 2 AMT modes for drives.
N O T I C E
In mode 2, the rotor rotates during the AMT progress.
Do not add any load on the motor in this AMT progress.

8 General Technical Data

8.1 Protection and Features

Electronic motor thermal protection against overload.
Temperature monitoring of the heat sink ensures that the drive trips if there is overtemperature.
The drive is protected against short circuits between motor terminals U, V, W.
When a motor phase is missing, the drive trips and issues an alarm.
When a mains phase is missing, the drive trips or issues a warning (depending on the load).
Monitoring of the DC-link voltage ensures that the drive trips when the DC-link voltage is too low or too high.
The drive is protected against ground faults on motor terminals U, V, W.

8.2 Mains Supply (L1/L, L2, L3/N)

Special Conditions

9 Special Conditions

9.1 Derating for Ambient Temperature

The ambient temperature measured over 24 hours should be at least 5 °C (9 °F) lower than the maximum ambient temperature. If the drive is operated at high ambient temperature, decrease the continuous output current. The drive has been designed for operation at maximum 50 °C (122 °F) ambient temperature with 1 motor size smaller than nominal.
Continuous operation at full load at 50 °C (122 °F) ambient temperature reduces the lifetime of the drive.

9.2 Derating for Low Air Pressure

The cooling capability of air is decreased at low air pressure.
C A U T I O N
INSTALLATION AT HIGH ALTITUDE
For altitudes above 2000 m (6560 ft), contact Danfoss regarding PELV.
Below 1000 m (3280 ft) altitude, no derating is necessary, but above 1000 m (3280 ft), decrease the ambient temperature or the maximum output current.
Decrease the output by 1% per 100 m (328 ft) altitude above 1000 m (3280 ft), or reduce the maximum ambient temperature by 1 °C (1.8 °F) per 200 m (656 ft).

9.3 Derating for Running at Low Speeds

When a motor is connected to a drive, check that the cooling of the motor is adequate. A problem may occur at low speeds in constant torque applications. Running continuously at low speeds – less than half the nomi-
nal motor speed – may require extra air cooling. Alternatively, select a larger motor (1 size up).
